Case: Corsair 500r
PSU: xion 1000 watt
CPU: amd fx 8350
GPU: 2x msi 6850's
RAM: kingston hyper x red 8gigs
Mobo:msi 990fxa gd80
Cooling: h100
I am quite new at overclocking and computers in general so bare with me :3
So basically i was testing my new cpu out, and i was trying to oc to a decent ghz. i was working my way to about 4.6 ghz at around 1.49 cpu voltage with everything else at auto, i had turned off cnq and some of the other functions.(which now that i think about it was probably what killed the mobo) it seemed quite unstable when i was testing it in prime so i decided to try upping the voltage to 1.5. when i had ran prime the next time after about 4-5 minutes the computer shut itself off. After a long diagnosis, it turns out to be the mobo. so i rma it and in the meantime (being inpatient as i am) i went to buy a new mobo, the crosshair 5 form z. i just got the comp all back together and i pressed power but all i got was no post and an ff on the debug moniter on the mobo. I had done some research about it and it could be numerous things wrong. So i tried everything, reseating, making sure mobo is not shorting, taking all components out and testing mobo first then ram ect... tested PSU with paperclip and it was good. The only thing i'm not 100% about is the CPU. I decided to take my old phenom 2 965 and swap it with the 8350. When i went to boot it worked. Maybe i killed the CPU and Mobo simultaneously? What you think?

 
Solution
uyes .. overvoltage and unstable voltage from PSU can kill .. 1. the HDD 2. DVDROOM 3. motherboard and other .. the CPU rarely damage by PSU because not use 12v :D .. the motherboard filtering this volt for support the CPU power .. see the indicator from soft (manual ) if the over 12.5v = dangerous, 5.5 = dangerous

the thing is it still works... Could it be that the psu went over a certain voltage and killed both cpu and vrm's?
